17
Q

epithelium embroyonic derivation

A

branchial arches

  • all are covered by ectoderm externally
  • endoderm lines internal surfaces
  • mesoderm is middle
18
Q

ectodermal origin tissues:

A

epithelium of all OUTSIDE stuff

  • mouth, nose, sinus, skin, hair, nails, glands that push stuff out
  • oil gland (sebaceous), sweat gland (eccrine), salivary
  • cornea
  • tooth
  • anal canal
19
Q

endodermal origin tissues

A
  • from mouth to anus, respiratory, liver, pancreas, endocrine gland
20
Q

mesodermal origin

A
  • kidney and ureter, adrenal cortex, gonnads
  • endothelium of blood vessels and lymph (vasculature)
  • mesothelium (pericardium, pleura, male internal organs, peritoneium)
21
Q

epithelium function

A
  • skin: barrier, thermo, sweat, make vit d
  • intestine absorb
  • glands secrete
  • teeth make enamel matrix
22
Q

simple vs complex or strat

A
  • 1 cell vs many cell
23
Q

columnar and squamous shape

A

column and pillow

24
Q

basement membrane

A
  • basal laminna, connects all epithelium to connective tissue
  • protein and polysacc only
25
Q

simple squamous

A
  • endo and mesothelium

- do gas exchange and protect

26
Q

simple cuboidal

A
  • glands, kidney tubules, thyroid follicles

- do absorption, secretion, ion transport

27
Q

simple columnar

A
  • intestinal lining, ameloblast
  • absorbption and secretion
  • nucleus is on the basal side
28
Q

stratified squamous epithelium

A
  • arranged in layers

- this is skin, hair nails, etc.

29
Q

pseudostrat columnar

A
  • respiratory track
  • appears layered (but only one)
  • ciliated
  • can have mucus secreting goblet cells
30
Q

transitional epithelium

A
  • can contract and expand

- only in bladder (thinn when full)

31
Q

cytokeratins

A
  • made by all epithelial cells

- intermediate filament proteins (give cell structure)

32
Q

epithelial cell polarity

A
  • apical is free surface with cilia/villi/etc
  • lateral surface is for cell adhesion
  • basal surface is for adhesion to mem
33
Q

apical specialization

A
  • microvili: actin
  • stereocilia: long vili
  • cilia: microtubule 9+2 thing made with tubulin

**all epi has at least 1 cilia

34
Q

tight junction

A
  • found near apical surface, lateral wall
  • protein complex where cell mem join together
  • determine and maintain polarity
  • no water and solute can go btw (paracellular) ONLY transcellular (pump nutrients thru)
35
Q

gap junctionns

A
  • connect cyto together
  • allow passage of small molecules btw cells so communication
  • 6 proteins each make connexin
36
Q

see photoes

A

mew

37
Q

exocrine vs endocrine gland

A
  • exocrine: duct stuff that goes outside

- endogrine make hormones that go into blood

38
Q

merocrine secretion

A
  • vesicle fuse to membrane on apical surfae and exocytosis of stuff
  • pancreas, salivary gland, tears
39
Q

apocrine secretion

A
  • secretion buds off of cell and goes off

- breast milk

40
Q

holocrine secretion

A
  • product and dead cell are released together

- oil glands

41
Q

unicellular gland

A
  • single cell makes the secretion

- goblet cell (pseudostrat)

42
Q

multicellular gland

A
  • a bunch of cells together secrete stuff

- lots of complex patterns
